If these images look like they're made from flowing, coagulated blood, that's because they are. Artist Jordan Eagles prefers to cover his canvasses with actual blood, which he procures from slaughterhouses. (We'll just have to give him the benefit of the doubt that the art isn't just a cover for a "Dexter"-like, secret serial killer lifestyle).
According to his website, the works are meant as "relics of that which was once living, embodying transformation, regeneration, and an allegory of death to life." They certainly deliver an eerie, dark-red glow. If they represent life, they also suggest that death is imminent.
